Set (Set) is an unordered collection of unique hashable values. Duplicates are not allowed.

Feature	Array	Set
Order	Yes	No
Duplicates	Allowed	Not allowed
Access	By index	Element existence check
Performance	Fast access by index, slow add/remove in the middle	Fast add/remove and existence check operations

// Array
var numbersArray: [Int] = [1, 2, 2, 3, 4]

// Set
var numbersSet: Set<Int> = [1, 2, 3, 4]
